Iowa State University Selects LiveRoof® for Memorial Union Green Roof

New 855-Square-Foot Green Roof Transforms Barren Rooftop into Beautiful Habitat

Ames, IA. and Spring Lake, MI., (April 18, 2012) — With funds allocated by its Government of the Student Body (GSB), Iowa State University (ISU) is installing an 855-square-foot green roof atop its historic Memorial Union. The LiveRoof® Hybrid Green System from LiveRoof, LLC (Spring Lake, Mich.) was selected for the project.


Roof Top Sedums, LLC (Davenport, Iowa), a LiveRoof® licensed regional grower and distributor, is growing plants for the Memorial Hall green roof. The colorful plant palette for the ISU project features four mixes of hardy, drought-tolerant groundcover plants, which display a variety of colors and textures, even during the fall and winter months. Roof Top Sedums and Central States Roofing (Ames, Iowa), a LiveRoof® certified installer, will oversee the installation by student volunteers.


ISU senior Miles Thompson, who studies horticulture with an emphasis in landscape design, has a strong interest in green roof technology and advocated for the project. When he learned that a green roof had been planned for the Memorial Union, but funding had not been approved, he took it upon himself to bring the issue to the GSB.
“We are proud of Miles and the other student leaders and impressed with their commitment to sustainability,” said Roxanne Nagel, general manager, Roof Top Sedums, LLC. “ISU helped instill our passion for the environment. We are honored they will now use the LiveRoof system to teach the next generation about green roof technology.”
Roof Top Sedums founders Roxanne Nagel and Teresa Nelson are both ISU alums. Nagel earned a bachelor’s of science in horticulture. Nelson earned a bachelor’s in landscape architecture.
